Showcasing the singer's signature falsettos and brimming with metal theatrics, "Abigail" tells the ill-fated story of Miriam and Jonathan La'Fey, a couple inhabiting an old family mansion riddled with ghosts foreshadowing the return of the tempered soul of baby Abigail. But it's the "Black Horsemen" that act as the main messengers, and thus grace the cover of this dark tale. Says King Diamond of the painting, "It was commissioned specifically for the album. The [artists] read the story, read the lyrics and then from that came the cover. The horse-drawn carriage came from their drawings [and we thought], 'Wow, that could be a really cool motif,' because 'Black Horsemen' is one of those main songs in that story. There were very little changes made before they started the painting; they could really visualize the story in a good way." As for the overall reaction, King recalls, "A lot of people heard us for the first time with that album , and (laughs) a lot of people told us they were scared when they heard the album; it gave them the creeps. And I guess the cover had a lot to do with that, too. It certainly had that creepy, classic horror feel. The best thing about that is you can prepare the listener through the cover for what is coming when you start playing the music. Had it been a red and white Danish flag on the front, I don't think the story and the music would come across in the same way, because it does something to it to look at that cover and start hearing music — it puts you in a certain pre-mood. Then the music can live up to the cover and vice-versa and you have that nice combination where it just gels."
